Li Ming, a modern social animal, died suddenly because he stayed up late to watch dramas. His soul accidentally traveled to the 14th year of Zhengtong (1449) and possessed Zhu Qizhen, the Yingzong of the Ming Dynasty who had returned after being captured by Wala. At this time, he not only had to face the humiliating status of a "captured emperor", but he also had to be involved in the machinations of Jingtai Emperor Zhu Qiyu, Wala's restoration conspiracy, and the "Tianshun Promise" puzzle that spanned three years.
A jade guide with the word "Tian Shun" engraved on it reveals a dust-laden secret - it is a forged "token of troop deployment" by Wala, and it is also a "military talisman" that can subvert the Ming Dynasty; a blood-stained book reveals the truth about the Tumubao Incident three years ago - the capture of Yingzong was actually a conspiracy between Wala and Emperor Jingtai? And the Queen Wang who faked her death in Kunning Palace, Mrs. Yu who always delivered sesame candies late at night, the mysterious man wearing a wolf head mask... Their appearance pushed Li Ming step by step to the center of the whirlpool of power.
From wearing a dragon robe and being laughed at as "crazy" to outsmarting powerful officials, from being ordered to be imprisoned and nearly dying to joining forces with Yu Qian to rectify the capital camp, Li Ming used modern thinking to break the situation and fight his way through the undercurrent of the palace. When he finally pieced together the complete secret of Yu Gui, he discovered that behind the "Appointment on the Meridian Gate Tower on the 15th day of the first lunar month of the second year of Tianshun" was a fatal trap set by Wala, and it was also the end of the fight between him and Emperor Jingtai's brother...
This is a story about rebirth, revenge and redemption - when the wheel of history rolls over the sand of Tumu Fortress, and when Yu Gui's poisonous blade pierces the brotherhood, can Li Ming rewrite the trajectory of the Ming Dynasty from prosperity to decline under the title of "Tian Shun"? And what kind of abyss will the "destiny" he touches with his own hands lead him to?
